Baltimore Gas & Electric (BGE) says its call to conserve electricity has ended, hours after a substation experienced an unplanned disconnection from BGE's electric grid.

Baltimore Gas and Electric Co. on Monday afternoon asked all customers to conserve energy “immediately” to reduce the chance of widespread power outages, according to a BGE post on social media. The potential outages are being caused by an “unplanned disconnection” between a power plant and the BGE electric system,

In an update on its website, BGE says that "a critical power plant [is] experiencing an unplanned disconnection from the BGE electric system."
